Material Design Tabs with Android Design Support Library

This is my third post where I continue to bring you more from the Design Support Library. Let’s look at adding a Material Design Tab strip for our apps with on scroll animations.

Tabs make it easy to explore and switch between different views. Provides a way for displaying grouped content. – source

Material Design Tabs made easy

You can see Material Design tabs popularly on the Play Store app, and more recently on WhatsApp as well (after their Material Design update).

Implementing the Tab earlier, we had to rely on external libraries. Let’s not forget the hide on scroll animations which we had to make ourselves.

Also read:

When you’re done reading this post, you’ll be able to create amazing Material Design tabs for your apps like the ones above. So let’s get to it!


Upon closer inspection on how the Tabs actually behave, you would have noticed each Tab upon being active brings in another screen (Fragment). We either tap a Tab, or swipe left or right to access the adjacent Tab. It sits anchored to the bottom of the Toolbar.

In essence, the entirety of those Tab screens are Fragments, which will be handled by a ViewPager (think of it like a gallery slideshow).

Before we dive into all of that, let’s setup our main layout first. Our layout structure will be defined like this.

< >

    < >

        < />

        <!-- The Tab rests directly below the Toolbar, attached below it -->
        < />


    <!-- Helps handing the Fragments to load for each Tab -->
    < />


Note the new widgets I’m using. These are from the Design Support Library. If you’re not familiar with these new widgets, I suggest you go through this post.

That’s the skeleton of our activity layout. Let’s start defining it now. Open your Activity’s layout.xml

< xmlns:android=""


            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

            android:layout_height="wrap_content" />


        app:layout_behavior="@string/appbar_scrolling_view_behavior" />


The scroll flags for the Toolbar specify how it must behave upon scroll (i.e. its animation). “scroll|enterAlways” says make my Toolbar react to scroll events. Hide it when scrolling down, and reveal it when scrolling back up.

This behavior will be indicated by our ViewPager which will be hold our Fragments. The Fragments hold our scrollable view. So when we scroll down a list, the Toolbar knows when to react.

Tabs attached below Toolbar

Setting up TabLayout

That’s our main layout. Open up the

Toolbar toolbar = (Toolbar) findViewById(;

 ViewPager viewPager = (ViewPager) findViewById(;

 TabLayout tabLayout = (TabLayout) findViewById(;

Start off by setting up your Toolbar. Then define the ViewPager. We’ll attach an adapter to in the setupViewPager() method. Finally define the TabLayout, and attach the view pager to it.

Remember that we must attach an adapter to the ViewPager before attaching the ViewPager itself to the Tab.

setupViewPager() method

Here I will simply initialize a ViewPagerAdapter (our custom adapter class which I will explain in a moment) and add 3 fragments to it. For simplicity’s sake, I will be attached the same Fragment thrice which different backgrounds.

In a real app scenario, you would be attaching different once. Say you got 3 tabs: Games, Movies, Books. Then you should be loading their respective fragments here in ORDER of the tabs.

private void setupViewPager(ViewPager viewPager) {
      ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
      adapter.addFrag(new DummyFragment(getResources().getColor(R.color.accent_material_light)), "CAT");
      adapter.addFrag(new DummyFragment(getResources().getColor(R.color.ripple_material_light)), "DOG");
      adapter.addFrag(new DummyFragment(getResources().getColor(R.color.button_material_dark)), "MOUSE");

Cat, Dog and Mouse (for the lack of better names) will be the names of my 3 Tabs.

Defining our Adapter

Remember that ViewPagerAdapter I told you about? Let’s create a class for it now, extend FragmentPagerAdapter and implement the required methods.

We need to store, first our Fragments itself, and the Fragment titles (for the Tabs). We’ll do this with a List.

private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();

Our entire Adapter class will look like this:

class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {

        public Fragment getItem(int position) {
            return mFragmentList.get(position);

        public int getCount() {
            return mFragmentList.size();

        public void addFrag(Fragment fragment, String title) {

        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);

Note that addFrag() is my own custom method which I’m using to add Fragments and its titles to the adapter.


Tab Fragment

Now that we’ve done all this, you might be wondering what is ‘DummyFragment’ and why its showing an error?

DummyFragment is to be your Fragment (obvious from the name), which holds the layout content. This is what we see when we swipe to each Tab. Ideally, you should be loading a different Fragment for each tab. The layout could be anything. But I don’t want to complicate things.

Just be sure for testing, to make a list long enough so that its scrollable, making the Quick Return animation work.

I encourage you to create your own layouts for the Tab Fragment. You could refer mine, but if you’re like “Hey, I can do this!”, then good job! Scroll down to the next section.

public static class DummyFragment extends Fragment {
       int color;
       SimpleRecyclerAdapter adapter;

       public DummyFragment() {

       public DummyFragment(int color) {
           this.color = color;

       public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
           View view = inflater.inflate(R.layout.dummy_fragment, container, false);

           final FrameLayout frameLayout = (FrameLayout) view.findViewById(;

           RecyclerView recyclerView = (RecyclerView) view.findViewById(;

           LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity().getBaseContext());

           List<String> list = new ArrayList<String>();
           for (int i = 0; i <; i++) {

           adapter = new SimpleRecyclerAdapter(list);

           return view;

tabs with list

Tab Listener

We can interact with the TabLayout and dictate what must happen when selecting a Tab, unselecting, reselecting and so forth.

While we’re staying on topic, let me show you how we can add such a listener to it.

tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            public void onTabSelected(TabLayout.Tab tab) {


                switch (tab.getPosition()) {
                    case 0:
                    case 1:

                    case 2:


            public void onTabUnselected(TabLayout.Tab tab) {


            public void onTabReselected(TabLayout.Tab tab) {


Note viewPager.setCurrentItem(tab.getPosition()) handles changing the Fragment based on Tab click.

Yes, all it takes is to use setOnTabSelectedListener with TabLayout.OnTabSelectedListener().

Just to demonstrate, I’ll be showing a simple Toast upon tapping each Tab. Note that this works not only when tapping the Tab, but also when swiping left or right! In essence, a Toast pops each time the Fragment loads into view.

23.0.0 FIX:

With the release of Android Marshmallow, libraries got updated to 23.0.0 including the Design Support Library. This update somehow broke the tab listener in a viewpager + tab combination. So if click listener for the tabs stops working for you, here is a suggested workaround for it, suggested by Chris Banes himself.

Material Design Tabs in Action

Let’s take a breath and break down what we’ve accomplished so far:

  1. Created our main TabLayout
  2. Initialized a ViewPager and attached an Adapter (ViewPagerAdapter) to it

  3. Attached the ViewPager to our Tabs

  4. Created the Fragment content to supply our ViewPager with

Finally with all that code behind us, lets run our app and see how it looks like.

That’s it! We’ve got some great looking Material Design Tabs (without a third party library), created the needed adapter and even got those snazzy on scroll animations for our Toolbar. Note the Tab underline highlight takes our colorAccent by default. Also, did you just notice we got those animations to work just by defining it in XML? No Java (Cheers!).

Thats what Android Design Support library allows us to do. Making the easy stuff easier.

  • In your codes, when tabs are clicked, ViewPager won’t change pages even you have set OnTabSelectedListener . You should set ViewPagerOnTabSelectedListener on your TabLayout. BTW, do you think it’s a bug inside TabLayout?

    • Hi Peter,
      Thanks for pointing it out. While the listener itself needn’t be changed, just add this line in the onTabSelected method, before the switch case:

      I’ve updated the post and GitHub repository. Thanks for following the post with a watchful eye.

  • Anuj Mody

    how to do with icons in tabs without text???

    • Use this:

      • Anuj Mody

        Thanks sir, and what if i want both txt and image then?

        • Its there in the same code snippet. Use setText(“YourTabName”);

          • Anuj Mody

            Thanks a lot sir it working fine now.Now i have one more doubt.I have differnt images when the user is on particular page of view pager.So how will i change the icon on page scrolled?

          • It is not recommended to keep changing the tab icon/text during use, as it would only confuse the user.

  • Sorry to hear you wasted a day finding that out. But glad you finally got it to work! Thanks for the pointer. Will make it clear for future readers.

    PS: Make sure you update ALL respective libraries together 😉

  • Mateusz Pryczkowski

    If in your fragment, you are not using RecyclerView, but you have simple ScollView – in this case hiding toolbar won’t work. In this case please use –

    • Correct. Thanks Mateusz for sharing a useful pointer!

      • Sayooj valsan

        Hi, I was following the example and Yes I dont have a RecyclerView. I just have a simple Listview in the fragment. How do I make the hiding work when I scroll ?

        • Hi Sayooj,
          Please migrate to RecyclerView

          • Akshay Labhshetwar

            yo can use NestedListView

            import android.content.Context;
            import android.util.AttributeSet;
            import android.view.View;
            import android.view.ViewGroup;
            import android.widget.ListAdapter;
            import android.widget.ListView;

            public class NestedListView extends ListView {

            private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;

            public NestedListView(Context context, AttributeSet attrs) {
            super(context, attrs);

            protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);

            int newHeight = 0;
            final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
            int heightSize = MeasureSpec.getSize(heightMeasureSpec);
            if (heightMode != MeasureSpec.EXACTLY) {
            ListAdapter listAdapter = getAdapter();
            if (listAdapter != null && !listAdapter.isEmpty()) {
            int listPosition = 0;
            for (listPosition = 0; listPosition < listAdapter.getCount()
            && listPosition heightSize)) {
            if (newHeight > heightSize) {
            newHeight = heightSize;
            } else {
            newHeight = getMeasuredHeight();
            setMeasuredDimension(getMeasuredWidth(), newHeight);


          • Hi Akshay,

            While that is a great and viable solution, I urge you to consider the advantages RecyclerView offers. Maybe giving this a read can help?

    Let’s say that I have a navigation drawer that selects either Frag1 or Frag2. How can I adapt this code so that Frag1 has the sliding tabs (like in this post), but Frag2 doesn’t?
    I have a StackOverflow question about this:

    Edit: Never mind, I figured it out! My xml layout wasn’t putting the ViewPager on that screen, so I couldn’t swipe!

    • Great. Glad to know you figured it out!

  • Kevin Chris

    I have a problem, When ever i slide the view pager slowly and if I take my hands in between the tabs indicator get stuck between the both tabs. I mean it is in middle. How to resolve this

  • Kevin Chris

    For me whenever I swipe slowly from one tab to another, in between if I stop swiping the tab indicator get struck in between the Tabs. Is there any solutions to fix this?

    • Hi Kevin,
      That behavior which you’re describing is weird. If you take a look at my Youtube video, I swipe past the Tabs slowly and it doesn’t get stuck in between. Could you try doing a clean rebuild? Make sure your updated all build tools and libraries to their respective latest versions as well.

    • Roberto Mirra

      Me too! Have you resolve?

  • Well, you certainly didn’t cross check against mine. Remove support v4. The card and recycler libraries are version 22.

    check mine

  • Poonam Kukreti

    Hi,I want to call tabs in navigation drawer how can i do that ?

    • You can use an interface that calls the tabs upon drawer item click

  • rethinavel

    it would be really nice if you share your dummy_fragment.xml BTW, Have you ever tested the webview in fragment works as well? The toolbar is not hiding if the fragment element is webview! could you please help me?

    • Your Fragment can contain any layout. Doesn’t matter what it is. I haven’t tested WebView personally, but the content doesn’t really matter. Do cross check your layout arrangement against mine. There is a GitHub link at the end.

      Also update your Design Support Library to 22.2.1

        @suleiman19:disqus can u pls help me i have Linearlayout + tabs +Viewpager now i want to whle layout inside scrollview once i m doing i m unable to create swiping between tabs

        • Could you please elaborate? Swiping between tabs work (as you can see in my post). I’d say you cross-check against my project (GitHub) once.
          Otherwise do post on StackOverflow so that I can take a look.

    • Depp

      As Mateusz Pryczkowski pointed out above, you might wanna wrap the webview in a NestedScrollView, it works for me~

  • Aibek Mamatov

    Hello, Suleiman19!
    I’ve a problem. The toolbar does not hide when i scroll recyclerview. I make all that how you made here. Can you halp me? If you whant i can send github url of my project.

    • Make sure you cross check your layout against mine. Especially scroll flags for Toolbar and layout_behaviour for ViewPager.
      Also update your Design Support Library to 22.2.1

      • Aibek Mamatov

        thank You very much! a solve my problem.))

  • igoticecream

    Hello, I’m following your tutorial and my fragments are PreferenceFragments… when i inflate them my toolbar wont hide while scrolling.

    I’m using LinearLayout and fragment to show my preferences.


    • The Preference Screen was never intended to have any such behavior such as the Quick Return. If you really want it bad, you can create a custom settings screen extending a normal Activity. Otherwise you should just focus on the Settings page behavior, rather than the animations.

  • Derrick Ozil Mugenyi

    Hey Suleiman19 can i have gridview in the fragment….and if i dont use recyclerView will the toolbar hide on scroll

    • I honestly haven’t tried a GridView Derrick, and wouldn’t want to give a false answer. As to my knowledge, any scrollable view would work.

      You could do a grid view using RecyclerView too. Just have to change the layout manager.

      • Derrick Ozil Mugenyi

        hey Suleiman thanks for the reply, i have managed to get the gridView in one of the tabs but i have tried so many ways to get the toolbar to hide on scroll but i have failed. PS: I havent used the recyclerView because it looks a bit complicated and long. The scrollFlags in the activity_main under Toolbar hasnt done any magic for me. But when i just design the Tabs and just include cardviews in the activity-main i am able to have the Toolbar to hide on scroll…. Any help will be great. Thanks

        • Maybe the GridView has some hiccups working with the Design Support Library. Like I said earlier, you can do a GridView with the RecyclerView as well. Its not at all complicated. I recently made a post you could follow specifically for this:

          Do note the only thing you need to change here is the LayoutManager from StaggeredGridLayoutManager to GridLayoutManager

  • JR

    Nice tutorial. Thank you so much. Saved me a lot of time with a very skilled approach.

  • Witalo Benicio

    Hey Suleiman19… is there a way to prevent Fragments to be recreated when changing pages?
    If i go to third page and went back to first, i can see my fragment loading views again.

    • use the onResume() and savedInstanceState()

  • marios zoutis

    Thank you very much for this great tutorial! Really helped me a lot! I have a question though. ViewPager seems to exceeds the height of the screen and goes beyond navigation buttons at the bottom. Is there a way I can make ViewPager view to stop at the bottom of the screen?

    • I need to see your layout before I can suggest a change. Make sure windowTranslucentNavigation in your styles.xml is set to false.

  • Honestly I haven’t experienced this. But I hope this link should solve your issue? Do take a look

  • igoticecream

    Hello. With the new support library 23.0.0, that tab listener stops working, weird. Any ideas?

    • BrandonWhite116

      I have noticed this too. Specifically after swiping the view pager then tapping the tabs. I haven’t found a workaround yet.

      • igoticecream

        Well it is a bug introduced with the new version of the support library. Check this workaround

        • Thanks for the pointer. Shall update the post so future readers can find this link.

      • To check this issue out, I updated all my libs to 23.0.0. But I don’t face any issue. Seems to work fine for me.

        • BrandonWhite116

          It started breaking for me when I swiped from position 0 to 1 then did a tab tap on position 0. The fix that igoticecream posted worked for me.

  • Yiyo Castillo

    Hey, this a really great post about tabs. I’m doing an app and I try to follow this guide, however I found with a difficult situation about tablayout so I want ask you for help.

    I want do an app with a NavigationView that replaces a framelayout (main content) with a fragment when an option is selected but I need that only some fragments have tabs (tablayout) and others no. Please take a look at Google Play Music to give you an idea.

    I could not find a good way to do that, can you tell me what would you do? Thanks

    • Hey there,
      Happy to know that you liked the post.
      About what you’re trying to achieve, I believe the simplest solution would be to use a new Activity for that.

      Make a BaseActivity that includes your Drawer. So any Activity you extend with BaseActivity will have the drawer.

  • erum hannan

    i m trying LinearLayout(have some buttons and imageview) + tabs + viewpager its working fine in case of fragments viewpager is swiping and tabs are also working fine but i want to put the above layout inside scrollview so that i can scroll the whole screen instead of only viewpager fragment bcoz my viewpager contains listview so listview has very limited vertical space in S3 devices to scroll the data thats why i want scrolling screen but once i m trying to use scrollview then my viewpager fragments are not displayed @suleiman19:disqus how to resolved ?

    • Try using a NestedScrollView instead.

  • Kevin Hackett

    Thanks for the great tutorial. The one question I have is – how do you set it, when you have a 3 tab layout, that the middle tab is the one that is open/selected every time the app starts or goes back to the main view from another activity?

  • Gitahi

    Thank you for putting together this tutorial. I’ve followed it and almost everything works perfectly, except for one thing. The tab titles get wrapped if they are too long to fit in the available screen space, see the screenshot attached. Instead, I would like for such titles to stay on one line but slide into the edge, much like how the Google Play Store home page behaves. I’m guessing this should only take a slight tweak and I’ve tried to play around with settings on the TabLayout to no avail. Any suggestions will be appreciated.

    • My bet is that the screen is too narrow to accommodate Tabs. How does it look in landscape mode?
      Try using tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);

  • Dhrumit Shah

    Hi thanks for the great sample. I have problem AppBarLayout scrolls up even if no data in CAT,DOG or MOUSE tab. Please get back on this as soon as possible.Thank you.

    • You’re welcome Dhrumit.
      I haven’t experienced any of these issues. Have you updated all libraries to their latest versions?

  • Use match_parent for both layout_width and height in your RecyclerView. Tell me if that resolves it for you.

    • Dhrumit Shah

      I have already used match_parent for both width and height . Same thing is happening in your sample also.

      • The best solution for this would be to not enable the Quick Return at all. This is because from the looks of the screenshot, that Activity doesn’t look very content heavy. You don’t need a Quick Return for that. Your content already has enough room 🙂

  • Евгений Мацюк

    Hello everbody!
    Maybe it’s trivial question but i can’t find answer.

  • Gurappa Ch

    Hi Suleiman,

    It works fine for me too as it is supposed to. But one issue is that the tabs does not move and become visible automatically. Say I have 5 tabs. 3 are visible and 4th one is half visible. When I select 4th tab, it does not come to visible. Same when i swipe. When I swipe to 5th page (of viewPager), 5th tab is still off the screen and not visible.
    How to make the tab layout keep scrolling automatically when swiping the view pager to right or left so that tab layout shows the currently selected tab in middle always. And rest of the tabe on it’s left or right ?
    Thanks again for the help with the article.

    • Gurappa Ch

      I tried with GRAVITY_FILL but of no use.

      • Gurappa Ch

        I could find solution for this. I had to do tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE) or app:tabMode=”scrollable” in XML.

        • Hi Gurappa,

          That is precisely the solution. Brilliant!
          Good to see you kept trying and found the solution on your own. Sign of a good developer 😉

  • Hi Gundeep,

    The latest Design Support library added a new scroll flag ‘snap. Add it to your Toolbar’s layout_scrollFlags.

    The same answer is already suggested by a user on StackOverflow. 🙂

  • 1. Cant use tabs inside Fragment instead of Activity: animation doesn’t work, also cant call activity.setSupportActionBar(toolbar) from my Fragment — this call makes error. I make an app using NavigationDrawer, so I have to use Fragments for all screens.
    2. I have many pages using similar layout with tabs (list screen → details screen with tabs). After the first time fragments in ViewPager does not visible. But sometime they may be shown (I don’t know the reason). Any suggestions? Thanks!

    • If you want it to work with Fragments, a simple idea is to add the TabLayout to your parent Activity. Then just do .setVisible(View.VISIBLE) for the Fragments that need Tabs, and View.GONE for those which don’t.

      Please update and see if that solves the issue.

    How do I change the title of the tab by an icon, like the Instagram tabs?

  • Thank you for that Susie. I’ve never faced this issue. Not able to reproduce it either, so I’m afraid I can’t be of help here.
    However, I’m sure this can help those who have this issue 🙂

    Hey, I made a TabLayout like this one with 2 tabs containing fragments with recyclerviews. Thing is my recyclerview items contain checkboxes. In each fragment I have a method that knows which items are selected.
    I want to have a button in the Parent Activity and call the fragment methods from it. Thing is when I do that it always returns null. Can you help me with that? Thanks a lot!

    • Hi Alex,
      You can fetch the Fragment in your Activity like this (assuming you have a ViewPager setup):
      YourFragment fragment = (YourFragment) pagerAdapter.getRegisteredFragment(position);

      Of course, the success of the call depends on whether your Fragment is active, so you’ll have to check for that before making a call.
      Hope that answered your question.

    Hello, Thanks for the great tutorial. So i build this App that gets “text” from my uni and i parse it.
    Each semester has different Lesson names,grades ,etc, can i achieve it with this tutorial?
    I get stuck at DummyFragment that displays in every tab the same Lessons
    Any ideas on how to get fragment/adapter to show different lessons for each semester?
    Thanks in advance!

    • Use the fragment’s setArguments() method to pass different “text” to each Fragment. Then based on that you can load your lessons accordingly.
      Hope that answered your question Antonis, and I’m glad the tutorial helped you.

    Though I used a different approached on the tabs and fragments, I was wondering how i could set the list items more rounder corners like yours.

    • Hi Jalal,
      The list items are simply using CardView 🙂
      Use the “card_view:cardCornerRadius” attribute in its XML and you’re good to go. Alternatively, you can check the code sample (end of post) for reference.

  • Hi Jack,
    That’s one amazing library! Really unique and brilliantly designed. I’m sure this will break the monotony of the ‘usual’ Tab Bars.
    Thanks for sharing my friend .
